IMPROVEMENT IN BEDSTEAD-FASTENING S.

Specification forming part of Letters Patent No. 16,093, dated November18, 1856.

To aZZ whom it may concern:

Be it known that I, SPENCER LEWIS, of Tiffin, in the county of Senecaand State of Ohio, have invented a new and useful Improvement inBedstead-Fastenings; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, forming part ofthis specification, in which Figure l is a section taken through axes ofrail and line at of Fig. 3 previous to tightening the joint. Fig. 2 is asimilar section after the joint is tightened. Fig. 3 is an elevation ofpost-square with a section of rail attached thereto by the fasteninghereinafter to be described. 7

Similar characters of reference in the several figures denote the sameparts.

The nature of my invention consists in constructing the fastening of aninclined pin running downward through the mortise and a perforation inthe tenon of the rail, combined with a swinging segmental plate on theface of the post-square and with a stud on the rail, downward pressureon the rail serving to bring its end against the face of the post, andalso drawing the segmental plate close to the rail and against the studon the same, so that a tight joint will be formed and the rail renderedincapable of turning.

In the drawings, P is the post, having in its square an oblong mortisem.

R is the rail, formed in a lathe and having cylindrical tenons 15 uponits ends. Obliquely downward through the post-square is bored a passagefor a pin B, a hole for the passage of this pin being also bored throughthe tenon t.

Upon the face of the post-square and capable of movement about a pinattach menta is the segmental guard G, whose inner edge is an arc of acircle of the diameter of the rail. On the upper portion of the rail isa stud b.

To fasten the rail to the post, the tenon t is inserted at the top ofthe mortise, as shown in Fig. 1, and the pin B passed downward throughchannel 0 and. the perforation in the mortise. Downward pressure on therail carries the tenon into the position shown in Figs. 2 and 3, theinclined pin B drawing the end of the rail close to the face of thepost. As the rail slips downward the guard G, turning on its attachmenta, adjusts itself to the rail, bringing its upper end in contact withthe stub b on the rail, and the fastening is completed. This guardserves to cover any portion of the mortise which might be exposed by theuse of a small rail, so that rails of any diameter may be employed. Theguard and stud, IIIOIGOVGI,SOIV6 to relieve the tenon from side strainon the pin, which by the turning of the rail might split the tenon.

What I claim as new, and desire to secure by Letters Patent, is

The inclined pin passing through post and tenon, as described, incombination with the segmental guard G and stud 1), operatingsubstantially as specified.

In testimony whereof Ihave hereunto signed my name before twosubscribing witnesses.

SPENCER LEWIS.
